Definitions
- the present invention relates to a vacuum cleaner suitable for, in particular, cleaning carpets and other flooring materials in buildings.
- bag vacuum cleaners may comprise a body that is set on wheels to enable it to follow the horizontal movements of an operator.
- the operator may pull the vacuum cleaner along by means of a hose that is swivelably connected to the body, and that, due to the suction of a motor provided in the body, carries dust and other dirt from a nozzle end of the hose to a dust collection chamber inside the body.
- the dust collection chamber may accommodate a disposable or reusable bag in which the dirt can be stored.
- the dust collection chamber may be accessible via a dust cover that is pivotably connected to the body.
- the dust cover is usually located at a top side of the body when the vacuum cleaner is in a working orientation.
- the vacuum cleaner may be provided with one or more lifting handles.
- a handle may be pivotably connected to the body, so as to allow it to be rotated back and forth between a folded position and a raised position. In the folded position, the handle may reside close to the body so as not to protrude there from, while it may be turned to its raised position when lifting of the body is desired.
- the lifting handle is preferably located at a top side of the body when it is in a working orientation.
- a desirable vacuum cleaner may preferably fulfil some further desires.
- Function for example, prescribes that the dust collection chamber of the vacuum cleaner is as big as possible. Generally, this translates into a vacuum cleaner wherein about one half (or less) of the body is occupied by the motor, while the other half (or more) is occupied by the dust collection chamber.
- the pivotable dust cover must thus extend across about half (or more) of the body.
- the lifting handle in its raised position, is disposed substantially above the center of mass of the body. Otherwise the body would start to rotate instantly when lifted off of the floor.
- a stable feel may further be imparted to both the handle and the dust cover by spacing apart their pivot points.
- the pivot points may preferably be disposed near opposite sides of the body so as to maximize the distance between them.
- the invention provides a vacuum cleaner comprising a body, said body including a dust collection chamber, and a dust cover, said dust cover being pivotably connected to the body such that it is movable between a first dust cover position and a second dust cover position.
- the dust cover In the first dust cover position, the dust cover at least partly closes off the dust collection chamber.
- the dust cover In the second dust cover position, the dust cover enables manual access to the dust collection chamber.
- the vacuum cleaner further comprises a lifting handle for lifting the vacuum cleaner.
- the lifting handle is pivotably connected to the dust cover such that it is movable between a first lifting handle position and a second lifting handle position. When the dust cover is in the first dust cover position, the lifting handle is substantially in line with the dust cover when it is in the first lifting handle position, while the lifting handle protrudes outward relative to the body when it is in the second lifting handle position.
- the battle for a place to connect to the body is thereby resolved.
- the pivot points of the lifting handle may reside under the dust cover, while the pivot points of the dust cover may reside under the lifting handle. Accordingly, the pivot points of the dust cover may for example even be disposed beyond halfway the body (e.g. in favour of enlargement or better accessibility of the dust collection chamber), without potentially pushing aside pivot points of the lifting handle from a position halfway the body. All pivot points may be arranged close to the sides of the body to ensure the stability of the lifting handle and the dust cover. Furthermore, visually, a single straight and narrow interruption line may extend between the dust cover on the one hand, and a top surface part of the body and the lifting handle on the other.
- Figs. 1 and 2 are schematic perspective views of different, known vacuum cleaners 1.
- the Figs. 1 and 2 illustrate known solutions to the problem of providing a vacuum cleaner with a lifting handle and a dust cover that are both pivotable around an axis at about halfway the body.
- a vacuum cleaner 1 typically comprises a hose 2 and/or a tube structure 4 having a nozzle 6 provided at an end thereof. For reasons of clarity, however, these elements are depicted only in Fig. 2 .
- the vacuum cleaners 1, depicted in an upright position, comprise a body 8 that is set on wheels.
- a third, more forwardly disposed wheel may provided at a bottom side of the body 8, such that, when the vacuum cleaner 1 is in a working position, it is supported by the three wheels that enable it to stably move across a level floor.
- the bodies 8 of the vacuum cleaners 1 comprise a motor, disposed in the back half thereof (in the upright orientation: the lower half), and a dust collection chamber, disposed in the front half of the body (in the upright orientation: the top half thereof).
- the dust collection chamber is covered by a dust cover 12 that is provided with a hose connection opening 14 to which a hose 2 may be swivelably connected.
- FIG. 1 Clearly visible in both Fig. 1 and 2 is the interruption line 22 in the top face of the body 8, which line demarcates the pivotable dust cover 12 from a non-pivotable, back top face part 28.
- the hinges of the dust cover are located below (in the upright orientation: behind) the top face part 28, less than optimally spaced apart.
- the body 8 of the vacuum cleaner 1 depicted in Fig. 1 features a circumferential, oval structure 16.
- a first lifting handle 18 is rigidly connected to the body 8, and its primary use it to enable a user to transport the body in its upright position, e.g. to and from a storage cabinet.
- a second lifting handle 20 is pivotably connected to the body 8.
- the interruption lines 24, which signal the split construction of the oval structure to enable the pivotability of the handle 20, are not in alignment with the interruption line 22. This is not beneficial to the appearance of the vacuum cleaner.
- oval structure 16 which seems to manifest itself as a separate identity that is formed on the body 8, and that protrudes from the basic outer dimensions thereof.
- the oval structure does, however, allow the pivot points of the handle 20 to be placed as desired, irrespective of the size of the dust cover, as the two do not interfere.
- the lifting handle 20 of the vacuum cleaner 1 depicted in Fig. 2 may, in contrast to that in Fig. 1 , be folded neatly into close abutment with the back side of the body 8, as shown.
- the vacuum cleaner 1 has been provided with rather bulky hinges 26.
- the hinges 26 project outward from the body, and thereby seriously impair the sleekness of its design.
- FIGs. 3 and 4 respectively show a side view and a top view of an exemplary vacuum cleaner 1 according to the present invention.
- the lifting handle 300 is in the first lifting handle position, while the dust cover 200 is in the first dust cover position. Both the lifting handle 300 and the dust cover 200 thus abut the body 8.
- What may catch the eye, in particular in comparison to the known vacuum cleaners 1 shown in Figs. 1 and 2 is the streamlined appearance of the device. Particularly striking is the single, substantially straight and narrow interruption line 100 that runs across the width of the body 8, from flank to flank. Near the flanks, the interruption line 100 bends somewhat, but this is not out of necessity.
- the bend was deliberately applied such that, in a side view, the interruption line 100 extends perpendicularly to the horizontally sloping line that separates the body 8 from the handle 300 and the dust cover 200.
- the interruption line 100 demarcates the dust cover 200 on the one hand from the lifting handle 300 and another top face part 28 of the body 8 on the other.
- decorative bands 202, 302 are visible.
- the first decorative band 202 is part of the dust cover 200
- the second decorative band 304 is part of the lifting handle 300. It is understood that the decorative bands 202, 302 help to hide the actual construction of the connection between the lifting handle 200 and the dust cover 200 from view. As can be seen well in Fig.
- the decorative bands 202, 302 join each other, in line, at the interruption line 100, which line spaces them apart by a narrow margin.
- the opposing edges of the decorative bands 202, 302 immediately adjacent to the interruption line 100 run substantially parallel to each other, thereby giving the interruption line part of its straight shape.
- FIG. 5 shows another side view of the exemplary vacuum cleaner 1 shown in Fig. 3 , now with the handle 300 pivoted clockwise towards its lifting position.
- the handle 300 can be pivoted without being hindered by the proximity of the dust cover 200. Pivoting the dust cover 200 in an anti-clockwise direction is also possible, as illustrated by Fig. 6 .
- lifting handle 300 backs away a little, which is a result of the fact that the handle is pivotably connected to the dust cover 200, at a point beyond that at which the dust cover itself is pivotably connected to the body 8.
- FIGS. 7-10 are exploded perspective views of the relevant parts of the lifting handle 300 and the dust cover 200, while Fig. 9 is a detailed perspective view of the hinge construction in action. Fig. 10 schematically illustrates some of the geometry involved.
- the dust cover 200 comprises two dust cover pivot arms 204.
- Each of these arms 204 comprises an extremity 206 at which it may be pivotably connected to the body 8.

- Fig. 10 schematically shows the interruption line 100 and the recess 208 in the dust cover pivot arm 202 (cf. Fig. 8 ). It is understood that the decorative band 302 pivots around the center of the recess 208. To enable such rotation, the depicted distance 'b' must be equal to or larger then the depicted distance 'a'.

- the number of plate members 212, 312 may vary per embodiment.
- a middle one of the three protruding plate members 312 provided on the lifting handle pivot arm 304 is receivable in a recess between the two plate members 212 of the dust cover pivot arm 204 to improve the stability of the connection.
- the plate members 212, 312 provided on both arms 204, 304 are arranged such that they interlock (i.e. the plate members of the lifting handle pivot arm 304 interlock with the plate members of the dust cover pivot arm 204).
- the middle one of the plate members 312 may be provided with a stop 314 that is disposed such that it engages an edge of the recess between the two plate members 212 when the lifting handle 300 is in its second lifting handle position (as shown in Fig. 9 ). This allows the lifting handle 300 to be fixed in its raised position.
- the plate members 212, 312 are typically flexible, a little force may suffice to move the lifting handle 300 back into its first position.

Abstract
A vacuum cleaner, comprising a body, a pivotable dust cover and a pivotable lifting handle, wherein the lifting handle is pivotably connected to the dust cover, and wherein the dust cover is pivotably connected to the body of the vacuum cleaner.
Description
- The present invention relates to a vacuum cleaner suitable for, in particular, cleaning carpets and other flooring materials in buildings.
- Typically, bag vacuum cleaners may comprise a body that is set on wheels to enable it to follow the horizontal movements of an operator. The operator may pull the vacuum cleaner along by means of a hose that is swivelably connected to the body, and that, due to the suction of a motor provided in the body, carries dust and other dirt from a nozzle end of the hose to a dust collection chamber inside the body. The dust collection chamber may accommodate a disposable or reusable bag in which the dirt can be stored. In order to be able to replace the dustbag when it is full, the dust collection chamber may be accessible via a dust cover that is pivotably connected to the body. For ease of use, the dust cover is usually located at a top side of the body when the vacuum cleaner is in a working orientation.
- To enable an operator to easily lift the vacuum cleaner, for example to transfer it between different vertical floor levels, or to vacuum places that cannot be accessed from floor level because the hose is too short, the vacuum cleaner may be provided with one or more lifting handles. Such a handle may be pivotably connected to the body, so as to allow it to be rotated back and forth between a folded position and a raised position. In the folded position, the handle may reside close to the body so as not to protrude there from, while it may be turned to its raised position when lifting of the body is desired. Naturally, like the dust cover, the lifting handle is preferably located at a top side of the body when it is in a working orientation.
- In addition to the mere presence of a dust cover and a lifting handle, a desirable vacuum cleaner may preferably fulfil some further desires. Function, for example, prescribes that the dust collection chamber of the vacuum cleaner is as big as possible. Generally, this translates into a vacuum cleaner wherein about one half (or less) of the body is occupied by the motor, while the other half (or more) is occupied by the dust collection chamber. To enable proper access to the dust collection chamber for replacing a full dustbag accommodated therein, the pivotable dust cover must thus extend across about half (or more) of the body. Another noteworthy functional desire is that the lifting handle, in its raised position, is disposed substantially above the center of mass of the body. Otherwise the body would start to rotate instantly when lifted off of the floor. A stable feel may further be imparted to both the handle and the dust cover by spacing apart their pivot points. The pivot points may preferably be disposed near opposite sides of the body so as to maximize the distance between them.
- In combination, these functional requirements lead the dust cover and the lifting handle to compete for structural junctures halfway the body, on opposite sides thereof. This problem is worsened when a design that is both sleek and functional is strived for. Sleekness may dictate a streamlined body profile, having as few interruption lines in the outer face of the body as possible. Those interruption lines that are practically necessary, such as for example interruption lines between the pivotable dust cover on the one hand, and the lifting handle or a fixed top face part of the body on the other, may preferably be straight and narrow. However, in order to enable both the dust cover and the lifting handle to be pivotably arranged at their preferred positions, bulky constructions and/or irregularly shaped interruption lines have thus far been accepted as a consequence of simple structural solutions.
- It is an object of the present invention to provide for a vacuum cleaner, having a lifting handle and dust cover, whose construction mitigates or overcomes the competition between the lifting handle and the dust cover for structural junctures halfway the body, thereby still allowing some or all of the above-mentioned functional and aesthetic desires to be satisfied.
- To this end, the invention provides a vacuum cleaner comprising a body, said body including a dust collection chamber, and a dust cover, said dust cover being pivotably connected to the body such that it is movable between a first dust cover position and a second dust cover position. In the first dust cover position, the dust cover at least partly closes off the dust collection chamber. In the second dust cover position, the dust cover enables manual access to the dust collection chamber. The vacuum cleaner further comprises a lifting handle for lifting the vacuum cleaner. The lifting handle is pivotably connected to the dust cover such that it is movable between a first lifting handle position and a second lifting handle position. When the dust cover is in the first dust cover position, the lifting handle is substantially in line with the dust cover when it is in the first lifting handle position, while the lifting handle protrudes outward relative to the body when it is in the second lifting handle position.
- A construction wherein the lifting handle is pivotably connected to the dust cover, and wherein the dust cover is itself pivotably connected to the body of the vacuum cleaner, allows the lifting handle and the dust cover to co-exist in something like a cross-relationship. The battle for a place to connect to the body is thereby resolved. The pivot points of the lifting handle may reside under the dust cover, while the pivot points of the dust cover may reside under the lifting handle. Accordingly, the pivot points of the dust cover may for example even be disposed beyond halfway the body (e.g. in favour of enlargement or better accessibility of the dust collection chamber), without potentially pushing aside pivot points of the lifting handle from a position halfway the body. All pivot points may be arranged close to the sides of the body to ensure the stability of the lifting handle and the dust cover. Furthermore, visually, a single straight and narrow interruption line may extend between the dust cover on the one hand, and a top surface part of the body and the lifting handle on the other.
- These and other features and advantages of the invention will be more fully understood from the following detailed description of certain embodiments of the invention, taken together with the accompanying drawings, which are meant to illustrate and not to limit the invention.

Furthermore, to improve drawing legibility, some elements in a figure may not be labeled in case the respective elements are clearly recognizable and have already been identified in one or more preceding figures.
- Reference is first made to
Figs. 1 and 2 , which are schematic perspective views of different, knownvacuum cleaners 1. TheFigs. 1 and 2 illustrate known solutions to the problem of providing a vacuum cleaner with a lifting handle and a dust cover that are both pivotable around an axis at about halfway the body. It is understood that avacuum cleaner 1 typically comprises ahose 2 and/or atube structure 4 having a nozzle 6 provided at an end thereof. For reasons of clarity, however, these elements are depicted only inFig. 2 . - The
vacuum cleaners 1, depicted in an upright position, comprise abody 8 that is set on wheels. In addition to the visible rear wheels 10 a third, more forwardly disposed wheel may provided at a bottom side of thebody 8, such that, when thevacuum cleaner 1 is in a working position, it is supported by the three wheels that enable it to stably move across a level floor. Thebodies 8 of thevacuum cleaners 1 comprise a motor, disposed in the back half thereof (in the upright orientation: the lower half), and a dust collection chamber, disposed in the front half of the body (in the upright orientation: the top half thereof). The dust collection chamber is covered by adust cover 12 that is provided with a hose connection opening 14 to which ahose 2 may be swivelably connected. Clearly visible in bothFig. 1 and 2 is theinterruption line 22 in the top face of thebody 8, which line demarcates thepivotable dust cover 12 from a non-pivotable, backtop face part 28. To enable thedust cover 12 to pivot around theinterruption line 22, the hinges of the dust cover are located below (in the upright orientation: behind) thetop face part 28, less than optimally spaced apart. - The
body 8 of thevacuum cleaner 1 depicted inFig. 1 features a circumferential,oval structure 16. Saidstructure 16, which may also fulfil a bumper function, incorporates twolifting handles first lifting handle 18 is rigidly connected to thebody 8, and its primary use it to enable a user to transport the body in its upright position, e.g. to and from a storage cabinet. Asecond lifting handle 20 is pivotably connected to thebody 8. As can be seen clearly, the interruption lines 24, which signal the split construction of the oval structure to enable the pivotability of thehandle 20, are not in alignment with theinterruption line 22. This is not beneficial to the appearance of the vacuum cleaner. The same may in fact be said of the entireoval structure 16, which seems to manifest itself as a separate identity that is formed on thebody 8, and that protrudes from the basic outer dimensions thereof. The oval structure does, however, allow the pivot points of thehandle 20 to be placed as desired, irrespective of the size of the dust cover, as the two do not interfere. - The lifting handle 20 of the
vacuum cleaner 1 depicted inFig. 2 may, in contrast to that inFig. 1 , be folded neatly into close abutment with the back side of thebody 8, as shown. However, to resolve the issue of connecting both of the oppositely pivotingdust cover 12 and handle 20 to a point about halfway the body, thevacuum cleaner 1 has been provided with rather bulky hinges 26. The hinges 26 project outward from the body, and thereby seriously impair the sleekness of its design. - Referring now to
Figs. 3 and 4 , which respectively show a side view and a top view of anexemplary vacuum cleaner 1 according to the present invention. InFigs. 3 and 4 , thelifting handle 300 is in the first lifting handle position, while thedust cover 200 is in the first dust cover position. Both thelifting handle 300 and thedust cover 200 thus abut thebody 8. What may catch the eye, in particular in comparison to the knownvacuum cleaners 1 shown inFigs. 1 and 2 , is the streamlined appearance of the device. Particularly striking is the single, substantially straight andnarrow interruption line 100 that runs across the width of thebody 8, from flank to flank. Near the flanks, theinterruption line 100 bends somewhat, but this is not out of necessity. Instead, the bend was deliberately applied such that, in a side view, theinterruption line 100 extends perpendicularly to the horizontally sloping line that separates thebody 8 from thehandle 300 and thedust cover 200. Theinterruption line 100 demarcates thedust cover 200 on the one hand from thelifting handle 300 and anothertop face part 28 of thebody 8 on the other. At the flanks of thebody 8,decorative bands decorative band 202 is part of thedust cover 200, the seconddecorative band 304 is part of thelifting handle 300. It is understood that thedecorative bands handle 200 and thedust cover 200 from view. As can be seen well inFig. 3 , thedecorative bands interruption line 100, which line spaces them apart by a narrow margin. The opposing edges of thedecorative bands interruption line 100 run substantially parallel to each other, thereby giving the interruption line part of its straight shape. - Surprisingly, and despite the fact that the
Figs. 3 and 4 seem to indicate otherwise, thedust cover 200 and thehandle 300 are pivotable in opposite directions. This is shown inFigs. 5 and 6. Fig. 5 shows another side view of theexemplary vacuum cleaner 1 shown inFig. 3 , now with thehandle 300 pivoted clockwise towards its lifting position. As can be seen, thehandle 300 can be pivoted without being hindered by the proximity of thedust cover 200. Pivoting thedust cover 200 in an anti-clockwise direction is also possible, as illustrated byFig. 6 . In thiscase lifting handle 300 backs away a little, which is a result of the fact that the handle is pivotably connected to thedust cover 200, at a point beyond that at which the dust cover itself is pivotably connected to thebody 8. - The construction that pivotably connects the
lifting handle 300 and thedust cover 200 together will now be examined in more detail with reference toFigs. 7-10 .Figs. 7 and8 are exploded perspective views of the relevant parts of thelifting handle 300 and thedust cover 200, whileFig. 9 is a detailed perspective view of the hinge construction in action.Fig. 10 schematically illustrates some of the geometry involved. - As can be seen, the
dust cover 200 comprises two dustcover pivot arms 204. Each of thesearms 204 comprises anextremity 206 at which it may be pivotably connected to thebody 8. Preferably, the dustcover pivot arms 204 are connected to thebody 8 such that a distance between the arms measures a dimension, e.g. a width, of the body. The relatively large separation of thearms 204, and hence of their pivoting connections, may impart a feel of stability to thedustcover 200 when it is in its opened position. The lifting handle 300 comprises two liftinghandle pivot arms 304. Each of these liftinghandle pivot arms 304 comprises anextremity 306 at which it may be pivotably connected to thedust cover 200, more in particular to a dustcover pivot arm 204. To this end, the dustcover pivot arms 204 may for example be fitted with acylindrical recess 208 in which a pivot pin (not shown) may be receivable. The pivot pin may also extend through aneye 308 provided in theextremity 306 of the associated liftinghandle pivot arm 304. Therecess 208 is preferably provided in an inner side of the dustcover pivot arms 204, so as to facilitate hiding the hinging connection from view. As well illustrated byFig. 8 , a liftinghandle pivot arm 304 may preferably be pivotably connected to a dustcover pivot arm 204 at a point (i.e. recess 208) beyond that a which the latter is itself connectable to the body 8 (i.e. at extremity 206). In addition, thepoint 208 where the liftinghandle pivot arm 304 connects to the dustcover pivot arm 204 is preferably located at a longitudinal point of the latter arm that is provided with the aforementioneddecorative band 302. This allows for a neatlynarrow interruption line 100. -
Fig. 10 schematically illustrates in more detail how the construction ofFigs. 7 and8 allows thedecorative bands Fig. 3 ) without impairing their mutual pivotability. In addition to saiddecorative bands Fig. 3 ),Fig. 10 schematically shows theinterruption line 100 and therecess 208 in the dust cover pivot arm 202 (cf.Fig. 8 ). It is understood that thedecorative band 302 pivots around the center of therecess 208. To enable such rotation, the depicted distance 'b' must be equal to or larger then the depicted distance 'a'. Here 'b' is the perpendicular distance from the straight edge ofdecorative band 302 to the center of rotation, while 'a' is the distance from said center to the corner ofdecorative band 202 around whichdecorative band 302 will pass during its rotation. The reason that the condition b ≥ a must be fulfilled is that 'b' is in fact the shortest distance between the center of rotation and thedecorative band 302. If this distance would be smaller than 'a',decorative band 302 would inevitably run into the aforementioned corner ofdecorative band 202.Fig. 10 makes it clear that, by making the distance 'a' smaller, the distance 'b' may be diminished as well. Practically, this means that moving therecess 208 upwards (towards the higher horizontal edge of the decorative band 202) may allow for anarrower interruption line 100. This explains why therecess 208 is preferably located at a relatively high position, close to the top edge of thedecorative band 302, as can be seen inFig. 8 . - Put together, a connection between the lifting
handle pivot arm 304 and a dustcover pivot arm 204 may look like the one shown in perspective inFig. 9 . As was already visible inFigs. 7 and8 , both the liftinghandle pivot arm 304 and the dustcover pivot arm 204 may comprise a number of spaced apart, substantiallyparallel plate members plate members Fig. 9 , a middle one of the three protrudingplate members 312 provided on the liftinghandle pivot arm 304 is receivable in a recess between the twoplate members 212 of the dustcover pivot arm 204 to improve the stability of the connection. To the same end, theplate members arms handle pivot arm 304 interlock with the plate members of the dust cover pivot arm 204). In an embodiment of the vacuum cleaner, the middle one of theplate members 312 may be provided with astop 314 that is disposed such that it engages an edge of the recess between the twoplate members 212 when thelifting handle 300 is in its second lifting handle position (as shown inFig. 9 ). This allows the lifting handle 300 to be fixed in its raised position.
